Note: Your transmitter has a 5-year lithium batteryto protect your pre-programmed data against maintransmitter battery failure. If you system reads 0.0volts, or has an unfamiliar display (service mode) or

your data resets to the factory defaults, return yourtransmitter to Horizon Service Center (see page 94)for lithium battery replacement.

CONTROL STICK LENGTH ADJUSTMENT

CHAPTER 1: TRANSMITTER CONTROLS • Helicopter continued

NECK STRAP ATTACHMENT1.6

To adjust the control stick length, use a 2mm Allenwrench to unlock the set screw located inside theend of the control stick. Turn the set screwcounterclockwise to loosen it, then turn the knurledportion of the stick to adjust the length.Counterclockwise will lengthen the stick andclockwise will shorten it. After the control stick(s)has been adjusted to suit your flying style, tightenthe set screw back.

For proper DSC hook-up and operation:1. Leave the transmitter power switch off. The

transmitter will not transmit any radio frequency (RF) in this position.

2. Plug the optional DSC cord (JRPA132) into the DSC port in the rear of the transmitter.

3. The encoder section of the transmitter will now be operational and the LCD display will be lit.

4. Plug the other end of the DSC cord into the receiver charge receptacle. Turn on the switch harness.

Note: When installing the optional charging jack(JRPA024) be sure to hook the charging jack receptacle securely into the switch harness charge cord.

Why you should use the DSC function:1. The DSC enables you to check the control

surfaces of your aircraft without drawing the fully operational 200mAh from your transmitter battery pack. Instead, you will only draw 70mAh when using the DSC function.

Note: You will need to purchase (separately) boththe DSC Cord (JRPA132) and the JR Deluxe SwitchHarness (JRPA001) to make use of the XP652 DSCFunction.

2. The DSC function allows you to make final adjustments to your airplane or helicopter without transmitting any radio signals. Therefore, if another pilot is flying on your frequency, you can still adjust your aircraft and not interfere with the other aircraft.

Note: Under no circumstances should you attemptto fly your aircraft with the DSC cord plugged in! Thisfeature is for bench checking your aircraft only.

There is an eye hook on the front of the transmitterfor attaching an optional neck strap (JRPA023). Theeye hook is precisely positioned (see Section 1.1) so

that the transmitter will be perfectly balanced whena neck strap is used.

It is important to correctly install the radio system inyour model. Please read and carefully follow thesuggestions listed below.

1. For added protection, wrap the Rx and the RxNicad in foam rubber that is at least 1/4” thick.

2. Run the Rx antenna through the fuselage andmake sure it is fully extended. Never cut orbundle your Rx antenna — this will decreaserange and performance.

3. Rubber servo grommets are included with yourradio system and should be installed in the servoflanges. The servos should then be mounted oneither hardwood rails or a plywood tray with themounting screws provided. Do not overtightenthe mounting screws. The flange of the brasseyelets should face down (toward the wood).

4. All servos must be able to move freely over thefull range of their travel. Make sure the linkagesdo not impede servo travel. A stalled servo will

drain the battery pack within a few minutes.5. Before installing servo output arms, make sure

the servo is in its neutral position.6. In the case of gas-powered model aircraft, mount

the receiver power switch on the side of thefuselage opposite the muffler to protect theswitch from exhaust residue. With other types ofmodels, mount the switch in the mostconvenient place. Make sure that the switchoperates freely and is capable of traveling its fulldistance.

7. With your model sitting on the ground and thetransmitter antenna collapsed, check thatyour system works at a distance of 75 to 100feet.If your system stops functioning at a distancethat is shorter than listed above, please contactthe Horizon Service Center for furtherinformation prior to flying your model.

The modulation select function enables your XP652to transmit to a variety of JR receivers that arealready, or may soon be, in existence. You canselect from either PPM (FM), Z-PCM or S-PCM,

depending on the central processing unit within yourreceiver to utilize existing receivers, or to upgrade yourXP652 flight pack for future models. Your systemcomes factory preset in the FM or PPM (Pulse PositionModulation) position so that it is compatible with theincluded R600 FM receiver.

Please refer to the receiver compatibility chart belowwhen selecting the modulation type for various JRreceivers.

Note: Once the proper modulation has been selectedfor a specific model number, the modulation type willremain the same for that model number, even duringmodel number/type changes. In other words, if youhave one model on FM/PPM and one model on PCM,the system will automatically change modulation typesonce the correct modulation has been selected for thatmodel.

FAIL-SAFE/HOLD FUNCTION IN Z-PCM MODULATION (System Mode)6.9

The Hold Function is automatically activated whenthe radio is turned ON and is in the Z-PCMmodulation.

This function stops (or holds) the servos in thepositions they were in just prior to the interference.Therefore, your airplane maintains the position held

immediately before the interference was experienced.When a clear signal is restored, the Hold Functionreleases, and control of the airplane returns to you.

If you would prefer your control surfaces to move to achosen position during a loss of signal, please refer tothe time delay/memory section below.

Hold (Z-PCM)

Accessing Fail-Safe/Hold (Z-PCM)

When the Fail-Safe Function is activated (i.e., whenthe signal is interrupted), the transmitterautomatically moves each servo to a preset position.The position that each servo assumes is determinedby you, as is the time length of interference that mustoccur before servo movement.

After the interference has ceased, control of theairplane returns immediately to you.

There are three time delays to choose from: 1/3 (0.3)second, 1/2(0.5) second and 1.0 second. These timedelays are the amount of time it takes, starting the

moment the interference occurs, until the servosassume their preset positions.

1. Press the MODE and CHANNEL buttonsimultaneously and hold.

2. Turn on the transmitter to enter the System Mode.

3. Press the MODE button until FST appears on the screen.

Note: If Fail-Safe does not appear on your LCD, it isbecause you are transmitting in PPM. Fail-Safe is notapplicable in the PPM mode. Refer to the ModulationMode Selection Section for more information.

The Fail-Safe/Hold Function is available only whenyou use the XP652 transmitter in either of thePCM modulations — S-PCM or Z-PCM. Thisfunction is designed to help minimize damage to

your airplane during a loss of signal to the receiver. Theservos either assume the fail-safe presets or hold thelast good signal position.

Note: In the PCM modulations, the Fail-Safe/HoldFunction cannot be totally disabled so that the servoswill react to interference in the same way as they do ina PPM system. This is only possible with the use of aPPM receiver and the transmitter in the PPMmodulation.

Note: Since the actual screen appearance varies,depending on the modulation of your radio, referto the appropriate modulation section which follows(Z-PCM, S-PCM).

As noted earlier, if you are in the PPM modulation, theFail-Safe/Hold Function is not applicable. Therefore,the Fail-Safe/Hold Function will not appear on yourLCD in the PPM mode.

Refer to the Modulation Selection Section for moreinformation pertaining to the broadcast signal of yourXP652 transmitter.

6. To exit the Fail-Safe Function, press the MODEand CHANNEL buttons simultaneously.

Note: These preset positions remain stored in thetransmitter’s memory until both the transmitterbattery pack and the lithium back-up battery havebeen removed (or until data reset has beenperformed). Therefore, you do not have to reset thefail-safe each time you fly. Should you want to re-adjust the fail-safe presets, access the Fail-SafeFunction and adjust the presets as you have justdone.

The Hold Function is automatically activated whenthe radio is turned ON and in the S-PCM modulation.

This function stops (or holds) the servos in thepositions they were in just prior to the interference.

Therefore, your aircraft maintains the position heldimmediately before the interference was experienced.When a clear signal is restored, the hold functionreleases, and control of the airplane returns to you.

The XP652 allows you to combine the hold and fail-safepresets for all six (6) channels on the receiver you canselect fail-safe or hold independently for all channelson your aircraft. In other words, some channels willhold their last clear signal position, while othersassume the preset position. Once the fail-safe hasbeen activated by signal interruption (interference), thetransmitter automatically moves the servos to a preset

position. The predetermined servo positions are set byyou. In the S-PCM fail-safe, the time delay (the amountof time it takes, starting the moment the interferenceoccurs, until the servos assume the preset positions) isfixed at .3, or 1/3, second.

Dual rate is available for the aileron and elevatorchannels. The purpose of this function is to allowfor in-flight selection of two preset servo travels foreach of these channels. The amount of travel is

adjustable from 0-125%. The factory settings for bothswitch positions (0 and 1) is 100%. Either position maybe selected as the low or high rate by placing theswitches in the desired position and adjusting thevalue for that position. Operation of these switches isdescribed in Section 6.3.

Different types of maneuvers require varying amountsof control movements. Snap rolls require large controlmovements, while smooth maneuvers like long slowrolls are best performed with smaller controlmovements. Dual rates allow you to change the controlmovements in flight at the flip of a switch. This allowsyou to execute maneuvers requiring both radicalcontrol movements and small control movementsduring a single flight.

DUAL RATE • Function Mode7.2



Programmable exponential adjustments are offeredon the aileron and elevator channels of your XP652system. Exponential is a function that allows you totailor the response rate of the controls as compared

to the stick inputs. The purpose of exponential is toreduce the sensitivity in the middle portion of stickmovement, while still allowing full travel at the end ofthe stick movement. In other words, the end result(travel) remains the same, although exponentialchanges the rate at which it achieves this travel.

The adjustable range of the Exponential Function isfrom 0–100%. Zero percent (0%) is linear stick controlwhich means that the response rate is equal

throughout the stick control. One hundred percent(100%) is full exponential. The larger the exponentialvalue, the less servo action, or sensitivity, you willnotice around the neutral setting.

Note: The Exponential Function operates inconjunction with the Dual Rate Function. It isimperative to understand the Dual Rate Function priorto adjusting the exponential values.

Exponential may be selected independently for eitherthe high or low rate (position 0 or 1), or both.

Sub-trim is an electronic trim that is available foreach of the 6 channels. Sub-trim is particularlyuseful as it allows the mechanical trim levers to bereturned to their neutral positions by adjusting

/changing the servo’s neutral position electronically,without the need to mechanically adjust the specificcontrol linkage. This allows the same mechanical trimlever settings between the five models you can control

with this radio system. Sub-trim can also allowadditional trim travel when mechanical trims do notprovide enough movement.

Note: It is recommended to use as little subtrim aspossible for adjustment. If more that 20-30 points arerequired, is it suggested that a mechanical linkageadjustment be performed.

The XP652 offers 3 separate pitch curves with 3adjustable reference points per curve. This functionallocates a separate pitch curve setting duringnormal, stunt, and throttle hold modes to

maximize flight performance. Once the pitch curves areestablished, each can be activated in flight using the 2-position flight mode switch and the throttle holdswitch.

Each of the 3 reference points of the pitch curve areindependently adjustable from 0–100%. These 3 pointscorrespond to the low, middle, and high positions ofthe throttle stick (collective).

The graph below shows samples of pitch curves in thenormal (N), stunt (S) and throttle hold (H) conditions.The factory preset values for all 3 pitch curves are: Low 0%, Middle 50%, and High 100%.

Adjustment of the throttle curve is very similar tothe pitch curve adjustment described in thepreceding section. A thorough understanding of thepitch curve section will make the throttle curve

section easier to understand.

There are two independent types of throttle curvesavailable — normal and stunt. The normal, or hover,throttle curve has 3 reference points (L,2, H) and thestunt, or flight, throttle curve has 2 reference points (L, 2).

The two throttle curves are activated by the flight modeswitch located on the top left rear corner of thetransmitter. The throttle curve is in the normalcondition when the flight mode switch is in the backposition. The throttle curve is in the stunt conditionwhen the flight mode switch is in the forward position.

The revolution mixing function combines tail rotorinput with the throttle/collective function tocounteract the torque created by the main rotorblades. When properly adjusted, the helicopter will

climb and descend without a tendency to yaw in eitherdirection.

Since the torque created by the main rotor bladesvaries with different throttle/pitch settings, it isnecessary for the tail rotor blades to change pitch atthe same time. The “U” or up mixing adjusts the tailrotor compensation from the mid to high throttle sticksetting. The “D” or down mixing adjusts the tail rotorcompensation from the mid to the low throttle sticksetting.

Thus, if you were to move the throttle from the low to

high positions, the tail rotor servo will move from the“D” to the “U” settings.

Revolution Mixing Set-up ProcedureFirst, set up the helicopter so that it will maintain astable hover with the tail rotor trim in the centerposition. Next, bring the helicopter into a steadyvertical climb. The body of the helicopter will move inthe opposite direction to the main rotor rotation.Increase the “U” or up mixing until the helicopterclimbs without the tendency to rotate. At a safealtitude, reduce the throttle. The helicopter willdescend, and the body will turn in the same directionas the main rotor blades. Increase the “D” or downmixing until the helicopter descends without thetendency to rotate.

RUDDER OFFSET • Function Mode7.10



The XP652 in helicopter mode offers one (1)programmable mix to be used for a number ofdifferent purposes. The functions allow mixing anyone channel to any other channel.

The mix can remain ON at all times, or be switchedOFF in flight using a number of different switches.(Refer to Chart A). Each channel is identified bychannel numbers 1-6 (i.e., 2 = aileron, 4 = rudder, etc.— see Chart B) The channel appearing first is knownas the “master channel,” or the channel to which youwant to mix. The second channel is known as the“slave channel,” or the channel that is being mixedinto the master channel. For example, ELEV-AILE

would indicate elevator to aileron mixing each timethe elevator stick is moved, the elevator will deflect,and the aileron will automatically move in thedirection and to the value input. Mixing isproportional, so small inputs of the master channelwill produce small outputs of the slave channel. Eachprogrammable mix has a mixing “offset.” The purposeof the mixing offset is to redefine the neutral positionof the slave channel.

The Elevator-Aileron mix mentioned above is mostcommonly used to help trim the helicopter for proper“loop tracking.” This type of mix should be used onlyby pilots who are comfortable with their programmingabilities with the XP652.

The Trim Offset Memory Function of your XP652allows you to test fly your aircraft and correct forany built-in trim requirements. After you adjust theaileron, elevator and/or rudder trim levers duringthe test flights, the trim levers are no longer in their

center, or neutral, positions. The use of trim offsetallows you to return the trims to their center, orneutral, positions without readjusting the controlsurface linkages mechanically.

This function is very useful when switching from modelto model. It allows your trims to remain in theirneutral positions while retaining their corrections.Using this feature, you can easily switch among thefive (5) model memories without the need to readjustfor each aircraft’s individual trim requirements.

Note: In helicopter mode, the trim offset memoryvalues stored will alter the servo position in bothnormal and stunt modes. Separate adjustments eachmode is not possible, except through the stunt trimfunction (page 83).

1. First, test fly your aircraft and adjust the aileron, elevator and/or rudder trim levers. After all adjustments have been made, land your helicopter. DO NOT adjust/reposition any of the trim levers at this time.

CAUTION: Do not attempt to adjust the Trim OffsetMemory Function while your model’s engine isrunning. Please stop your aircraft’s engine beforeentering the Function Mode.

93 XP652 MANUAL Important Information

IMPORTANT INFORMATION

Radio controlled models are a great source ofpleasure. Unfortunately, they can also pose apotential hazard if not maintained and operatedproperly. It is imperative that you install your radiocontrol system correctly. Additionally, your level of

piloting competency must be high enough to ensurethat you are able to control your aircraft under allconditions. If you are a newcomer to radio controlledflying, please seek help from an experienced pilot oryour local hobby shop.

Listed below are some safety Dos and Don’ts that mustbe followed by all pilots:

• Ensure that your batteries have been properlycharged prior to initial flight.

• Keep track of the time that the system is turned onso that you will have an idea of how long you cansafely operate your system.

• Perform a ground range check prior to the initialflight of the day. See the “Daily Flight ChecksSection” below for information on how to do so.

• Check all control surfaces prior to each takeoff.

• Use frequency flags.

• Do not fly your model near spectators, parkingareas, or at any other area that could result ininjury to people or damage of property.

• Do not fly during adverse weather conditions. Poorvisibility can cause disorientation and loss ofcontrol of your aircraft. Strong winds can causesimilar problems.

• Do not fly unless your frequency is clear. Warning: Only one transmitter at a time canoperate on a given frequency. If you turn on yourtransmitter while someone else is operating amodel on your frequency, both pilots will losecontrol of their models. Only one person can use agiven frequency at a time. It does not matter if it isAM, FM or PCM — only one frequency at a time.

• Do not point the transmitter antenna directlytoward the model. The radiation pattern from thetip of the antenna is inherently low.

• Do not take chances. If at any time during flight youobserve any erratic or abnormal operation, landimmediately and do not resume flight until thecause of the problem has been ascertained andcorrected.

1. Check the battery voltage on both the transmitterand the receiver battery packs. Do not fly below9.0 volts on the transmitter or below 4.7 volts onthe receiver. To do so can cause a crash of youraircraft.

Note: When you check these batteries, ensure thatyou have the polarities correct on your expandedscale voltmeter.

2. Check all hardware (linkages, screws, nuts, bolts)prior to each day’s flight. Be sure that bindingdoes not occur and that everything is properlysecured.

3. Ensure that all surfaces are moving in the propermanner.

4. Perform a ground range check before each day’sflying session. The range check should be asfollows:

• Do not extend the transmitter antenna at thistime. Turn the transmitter “on.”

• Turn the model “on.”

• Slowly walk away from the model while movingthe control surfaces. The aircraft should functionproperly at a distance of 75–100 feet.

5. Just prior to starting your aircraft, turn “off ” yourtransmitter and then turn it back “on.” Do thiseach time you start your aircraft. If any criticalswitches are on without your knowledge, thetransmitter alarm will warn you at this time.

6. Ensure that all trim levers are in the properlocation.

7. Check to be sure that all servo pigtails and switchharness plugs are secured in the receiver. Also,make sure that the switch harness movescompletely in both directions.
